I COVERING FOR TOP ROLLS OF SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 352,911, dated November23, 1886.

Application filed June 26, 1886. Serial No. 206,321. (Model) I To allwhom' it may concern:

Be it known that I, THOMAS E; DUNGAN, a citizen of the United States,residing at Frankford, Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented a certain new and usefulImprovement in Goverings for Top Rolls of Spinning-Machines, of whichthe following is'a full, clear, and exact description of the naturethereof, suflicient to enable others skilled in the art to which myinvention appertains to make and use the same, reference being had tothe accompanying drawings, making part of this specification.

Now, the object of my invention is to pro-' duce a cheap, practical, anddurable covering for what are known in machinery for spinning cotton,W001, 800., as the ftop rolls or rollers,

as a substitute for leather covering; and my invention consists in acovering for drawingrolls composed of a thin cylindrical seamless woodenshell or hollow sleeve, which may be secured in any well-known mannerupon the outside of a metallic-shell roller or solid roll insubstantially the same manner and occupying the same relative positionas that of the leather covering'at present and heretofore in use.

My invention also consists in the peculiar construction of the shell orsleeve; and it also consists in a drawing-roll provided on its outersurface with a covering composed of the aforesaid shell or sleeve.

In the sheet of drawings annexed, Figure l is a side view of one kind ofa spinning-roller that is used upon the top, having integrallyjoinedsolid cores having solid trunnions, showing my improved covering placedthereon. Fig. 2 is a longitudinal vertical section of the same. Fig. 3is an'end view thereof. Fig. 4 is a cross-section on line as x ofFig. 1. Fig. 5 is a side view of a spinning-roll used also on the top,and is constructed with a metallic sleeve which revolves upon a solidshaft, and shows my improved covering placed thereon. Fig. 6 is alongitudinal vertical section of the same. Fig. 7 is an end viewthereof; Fig. 8 is a cross-section of Fig. 5 on line y y. V Fig. 9 is alongitudinal vertical section of a modified form of, covering shownapplied to what is known as a shell roller. Fig. 10

is a cross-section on line a z of the same.

Similar letters refer to like parts in the several views.

Referring to the drawings, A represents what is known to the art as asolid. trunnioned roller, and B designates the wooden shell or hollowsleeve-covering for the same.

C in the drawings refers to the metallic sleeve, which revolves looselyupon the solid core or shaft H, and having secured upon the saidmetallic cylinder or hollow sleeve a similar wooden cylindricalcovering, B-

As hereinbefore stated, the object sought to be covered by my inventionis to entirely dispense with that form or mode of covering now andheretofore in use, in which a I covering of loosely-woven cloth is firstcemented to the outside of the cylindrical metallic shell or solidtrunnioned roller, and a thin tube of leather forced tightly over thesame, in a man-.

ner well known to those skilled in the art of what is known asroller-covering.

By substituting the wooden shell or tube for the cloth and leather,greater efficiency is seas will readily receive a very smooth andpolished face, and, besides, possess an elastic and flexible nature, toinsure as much adaptation as possible to the face of the fluted rollerwhich revolves it in the spinning of yarn. I In Figs. 9and 10,respectively, I have illustrated a modification in the construction ofthe wooden shell or sleeve B, and shown the same applied to a hollowroller, the outer face of which roller would have a smooth surface thesame as in the solid roller; but the said wooden shell or sleeve Bisshown bored, or by some as new and desire to secure by LettersPatent-- 1. As a new article of manufacture, a covering fordrawing-rolls, consisting of a thin seamless tube of wood, substantiallyas described.

2. As a new article of manufacture, a covering for drawing-rolls,consisting of a thin seamless tube of wood hollowed out between itsends, substantially as described.

3. The combination, with a drawing-roll, of a covering composed of aseamless sleeve formed of wood, substantially as described,

, and for the purposes set forth.

4-. The combination, with a drawing-roll, of a covering composed of aseamless sleeve formed of wood, the inner side of said sleevebeinghollowed out, substantially as described, and for the purposes setforth.

In testimony that I claim the foregoing as 1 my invention I havesubscribed my name in the presence of two witnesses.
